2 Claims.

The instant invention relates to supporting racks and more particularlyto folding racks especially adapted for attachment to an angularlydisposed support.

The primary objects of the present invention are to provide a rack forsupporting books, papers or the like which is adapted for attachment toan angularly disposed support such as a tiltable desk top; to providesuch a rack which may be folded and concealed when not in use; toprovide such a rack which is particularly well adapted for attachment totiltable tops of school desks of the general character shown anddescribed in my co-pending application for patent, Serial No. 759,038filed Dec. 24, 1934.; and to provide such a rack which may be readilyinstalled for use, a rack which is utilitarian in use, and a rack whichis economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanyingdrawing, wherein:

Figure 1 is a fragmentary front elevational view of an angularlydisposed support such as a tiltable top of a school desk and showing thefolding rack of the instant invention unfolded for use;

Figure 2 is a fragmentary side elevational view thereof showing indotted lines the rack folded upwardly and rearwardly in its concealedposition when not in use; 7 I

Figure 3 is an enlarged fragmentary end elevational view of the rackwhen in its upwardly and rearwardly folded and concealed position;

Figure 4 is a fragmentary sectional view of the rack on line 4- 4 ofFigure 1 when the rack is in its upwardly and rearwardly foldedposition;

Figure 5 is an enlarged fragmentary end elevational view of thepivotally connected supporting arm for the rack;

Figure 6 is a fragmentary front elevational view of that part of thestructure which is shown in Figure 5;

Figure 7 is a sectional view on lines 'I-'I of Figures 2 and 8;

Figure 8 is an enlarged fragmentary end elevational view of the rack andits pivotal connection with its supporting arm when the rack is inunfolded position for use;

Figure 9 is a fragmentary front elevational view of that part of thestructure which is shown in Figure 8; and

Figure 10 is a sectional view on line Ill-l0 of Figures 2 and 8.

Referring to the drawing in which like parts of the structure shown aredesignated by the same numerals in the several views, an angularlydisposed support it such as a tiltable top of a school desk of thegeneral character shown in my co -pending application for LettersPatent, Serial No. 759,038, filed Dec. 24, 1934, has its rear surface Itprovided with a trough l2 adjacent its upper marginal edge.

A pair of brackets l3, preferably of metal, each having a flanged lipHi, are respectively secured to the rear surface of the support l0adjacent the marginal ends 15, H5 thereof and intermediate theirlengths. A pair of arms ll, [8, likewise preferably of metal, arerespectively pivotally secured to the lips M of the brackets l3 as by apintle l9 and to the free ends of each arm are pivotally secured amember 20 having an inwardly turned portion 2|.

A cross member 22 of metal or other suitable material of sufiicientwidth to form a supporting rack for books, papers and the like isrigidly secured to the oppositely disposed inwardly turned portions 2iof the pivoted members 20 as best shown in Figures 8, 9 and 10.

In operation, it will be assumed that the cross member 22 is in theunfolded position shown in full lines in Figures 1 and 2. In thisposition, the cross member is adapted for use as a supporting rack forbooks, papers and the like. When this supporting rack is no longerdesired for use, the arms ll, I3 may be folded upwardly and parallelwith the ends l5, [6 of the support It] and the cross member 22thereafter folded downwardly behind the upper edge of the support andinto the trough, all as best shown in Figures 3 and 4 and as isindicated by dotted lines in Figure 2.

It will thus be seen that the supporting rack for books, papers and thelike herein shown and described is particularly well adapted forattachment to tiltable tops of the school desk type and when attached toa tiltable top of the character herein shown and described, the rack maybe folded upwardly and thereafter downwardly to a concealed positionwhen not desired for use.

While but one specific embodiment of this invention has been hereinshown and described, it will be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as defined by the following claims.

I claim:

1. A supporting rack adapted for attachment to an angularly disposedsupport comprising a pair of arms pivotally connected at one end intermediate the ends of the support and a cross member pivotallyconnected adjacent the free ally connected at one end intermediate theends of the support and a cross member pivotally connected adjacent thefree ends of the arms whereby the arms may be folded upwardly parallelWith the ends of the support and the cross member thereafter foldeddownwardly behind the upper edge of the support and into the trough.
